We plan to use Amex KR1025 daily data file and upload the same using PRCC in to our R/3 Enterprise version 4.7. When we receives the file from Amex, we have developed a customised conversion program that converts this data file into a SAP acceptable format file before it can be uploaded, and during this process, I realised that accounting run number is generated with a static number from Amex file and by adding month and date of the file from file header. For example, company code 'AB12' will have an id as 020527 given to us by Amex and the conversion program adds month and date as 0708(07 being july and 08 being file date). Now I imagine that currently it will work but in future ie, next year there will be an issue with this when it repeats the same number as this number will be repeated again when we upload for file for July 8th, 2011.
Wondering if anyone out there who could share their experience(s) concerning Accounting Run Number in Amex KR1025 data file.
